Formula
Raw capacity = (total area − non-guest area) ÷ area per guest. Practical capacity = floor(raw capacity × (1 − buffer rate)).
What the result means
The main result is a planning estimate based on your inputs. Supporting figures show the intermediate values so you can identify which assumptions have the largest effect.
Planning tool only. Verify contractual, code, occupancy, pricing, tax, and safety requirements with the appropriate professional or authority.
Example calculation
A 5,000 sq ft venue with 1,200 sq ft reserved, 15 sq ft per guest, and a 10% buffer supports about 228 guests.
Tips for better results
- Follow the venue's posted occupancy and local fire-code limit if it is lower.
- Measure usable area after confirming table style, dance floor, stage, and service aisles.
- Add accessibility and emergency-egress space before assigning guest seating.
